CULVERT.

i To all wlom it may concern v Be it known that I, JULI S H. SoHLArLY;

' or c'ulvert, and the invention particularly Iesides in the means for Connecting the said sections together in the manner stated.

The Object of the invention is to provide a simple, cheaply constructed, strongand durable culvert adapted to be shipped or -transported ina nested Condition and to be readily set up, connected together, and put in place .wit-h the aid of the simplest tools, the operation of Connecting the sections being so easily performed as not to require the services of a skilled workman.

I .attain this-Object, together with other objects readily apparent to those skilled in the art, by the construction illustrated in the :accompanying drawing, in which- Figure 1 illustrates a culvert composed of V complementary sections arranged as top and bottom sections to form a culvert, one of said sections being removed to further disclose the construction. Fig. 2 is a persp-ective view of two of the lower sections so arranged as to illustrate the manner in which the ends of longitudinally adjacent bottom sections overlap at their meeting edges, where that form of culvert is used in which the compound fianges terminate short of one end of the section. F ig. 3 is a transverse section-al view through upper and lower sections properly joined. Fig. 4 is a perspective view of two of the lower sections arranged to illustrate that form o-f the culvert in which recesses are pressed outwar'dly in the comeithercorrugated or plain, the corrugated Specification of Letters Patent.

form being preferred because of its greater strength. In thedrawing the numeral l indicates one of the upper complementary sections. These sections are substantially semicylindrical and may be provided with circumferential corrugatio-ns, as shown. Along the side edges of each top section is provided theintegral, la-terally extending flange 2 whichmay be either plain or co-rrugated, the ,plain fiange being preferred because of the fact that by its use a neater jo-int may be made. The drawing discloses the const-ruction in which the plain flange is employed, the circumferential corrugat-ions terminating at the line where the met-al is bent lat erally to form the flange. The lower complementary sections 3 are substantially semi-cylindrical and are provided with integral, compound flanges consisting of a laterally extending flange ,4 and the integral flange 5 arranged at right angles to the flange 4, the flange 5 being adapted to *be bent or foldecl down upon the flange 4 for thepurpose of engaging and holding in place the fianges 2 of the complementary top section as hereinafter more fully explained.

The compound flanges on the lower sections may extend along the side edges from end 'to end of .eachsectio-n if desired. It will be understood, however, that in lapping the ends of longitudinally adjacent lower sections the compound flanges will also be lapped, and in, some instancesthis lapping of the fianges with the incidental doubling of-the metal and unevenne ss may be considered objectionable. To avoid this objectionable feature I provide the method of constructionillustrated in Figs. 2, 4 and 6. In the construction 'illustrated in F ig. 2 i

the compound flanges at one end of each lower section are cut .away or made to ter- `minate short of the end of the section, as

illustrated at 6. This .will permit the flanges of longitudinally adjacent lower'sect-ions to abut end. to end instead of overlapping each other althoughthe ends of the culvert sections exclusive of the flanges'will oVer-lap' each other as usual. In Fig. 4 the compound flanges at one endof one section are provided with the vrecessed, portions 7, the fiange 4 being pressed downwardly substantiallythe thickness of the sheet metal of whichothe sections ,are constructed and the flange being pressed out-wardly the same distance. The flanges of the longitudinally adjacent lower section will then lie within the said recesses when the ends of the sections are over-lapped, producing the arrangement illustrated in Fig. 5 and providing a smooth and even flange 4 extending throughout the over-lapping sections and permitting the flange 2 of the conplementary section to lie fiat against the flanges 4- of the over-lapping lower Sections. ll`he recess 7 also permits the flanges 5 of the twolower Sections to be so alined that when the flanges 5 are folded or bent down upon the flange 2 of a complementary section a neater joint or seam will 'be produced.

In Fig. 6 the recesses 8 in the flanges 4: and 5 are pressed inwardly instead of outwardly, the arrangement producing to a certain eX- tent, the reverse arrangenent from that shown in Figs. 4: and 5. The recesses 8 do not produce quite so smooth and even a joint or seam as the recesses 7, but by means of their use the over-lapping eompound flanges are caused to make a neater joint or fold at their over-lapping portions, which is the point in the seam or joint requiring the greatest strength and* most careful construction. a

It should be stated that the flanges 2 are of approximately the same Width as the flanges 4:, as will be reaclily understood from an inspection of Fig .3. It will be noted also, that if the Sections are provided with circumferential corrugations the end corrugations of longitudinally adjacent Sections will be adapted to engage each other where the said sections are over-lapped, thus producing a strong and substantial joint.

In arranging the complementary Sections it is well to lap the meeting ends of longitudinally adjacent sections at a point inter mediate the ends of the com plementary section, thus breaking the joints and securing st-ructural advantages.

3l`he various Sections having been provided as hereinbefore described, the method of Connecting said Sections together to form a culvert is as follows: An appropriate number of lower Sections are arranged with the meeting ends of longitudinally adjacent sections over-lapping; the compound flanges upon said lower Sections will then form a continuous ledge upon which the lateral flanges of the top or complementary Sections may rest. The top Sections are then arranged in a longitudinal series upon the lower Sections, the meeting' ends of adjacent top sections being over-lapped substantially as in the case of the lower sections and the various sections being so arranged as to break joints, as hereinbefore described. It is then only necessary to use a hammer or other suitable tool to bend over or fold down the flanges 5 upon the flanges 2, as illustrated in Fig. 3, thus producing a firm and substantial connection between the sections. a

While I have shown and described upper and lower Sections, the upper sections pro vidcd with simple fianges and the lower Sections provided with compound flanges, it is evident that the sections might be formed so that each section would be provided with one simple flange and one compound flange, so that aculvert could be produced from any two of such Sections which might be in stock.

It should also be noted that a culvert might,

be constructed with Similar means of fas tening' the sean where there is only one seam to the complete culvert, the same not being` made in sections and likewise more than two sections may be employed if it is found practical or expedient to do so.

While I have described the method of connecting the sections as above l: do not desire to be limited to this method. It is evident that the flanges 5 might be folded down practically into the position illustrated in Fig. 3 and that the flanges of the sections l might be slipped into position between the fianges 4 and 5 of the complementary sections by starting the said flanges 2 into the grooves'between the fianges 4 and 5 at the end of the section and sliding the Sections relatively to each other until the approprate relative position has been attained.
